Hi there!
Found the site roundabout through a Roll20 annoucement...
Was active some years back, playing in Woldian Games (left when management decisions started making no sense), PBM.com (best experience was Blue Giant there) and my home-made crazy PBF Ars Magica no-rules multi-faction campaign.
After a few years I was put off by PBF/PBEM a because of numerous non-starters, weird "mature" games, and snobbery regarding "writing skills".
Game-wise, I really appreciate a style that puts the focus on interesting, short posts that leverage the written medium without going into personnal novellas or mood boards.
I like light, tongue-in-cheek universes, because it guarantees no boring posts, just as well as stern, serious stuff and oddball ideas.
Personnal faves, though mostly secret desires: old-school Paranoïa, Shadowrun (with replacement rules...), Autoduel, Conan and Cugel (the universe, not necessarily the games...).
I don't do 5E.
